The application of SSWT reagents creates minerals, including: exchange and bond precipitates; pH-log dependent complex precipitates; hydroxyapatites; and apatite's complexes with Chlorides, Iron and/or Aluminum. Depending on the waste character and composition, target Lead minerals such as chloropyromorphite and corkite are formed as these are extremely insoluble, nontoxic and stable.  Process methods and chemical supply equipment is engineered, designed and supplied by Soil Solutions, providing a custom solution for your brownfield.   [![Get Your Treatment Evaluation](https://no-cache.hubspot.com/cta/default/8211740/dedeb450-2725-4964-ba40-d2f95e577b20.png)](https://cta-redirect.hubspot.com/cta/redirect/8211740/dedeb450-2725-4964-ba40-d2f95e577b20) #### Advantages - Single step, safe and rapid application method - Chemical supplies and support services provided by Soil Solutions - Commonly <1% wwb weight increase to stabilized material - Molecular packing often reduces waste volume up to 5% - Low cost, field-proven technology - No pug mill or ex-situ mixer equipment required - Wet method controls dust and metals dispersion - Rapid application up to 1000 TPD per two-man crew  - No curing time required due to rate of mineral formation - Can be applied at any depth on material surface - Suitable for small restricted work areas  - Can be applied on waste and material piles at any slope or elevation ## Resources - **[FESI-BOND™ Datasheet](https://www.soilsolutions.info/hubfs/fesi%20(2).doc?hsLang=en)** - **[FESI-BOND® WET Application Treatment Alternatives](https://www.soilsolutions.info/hubfs/FESI-BONDR%20WET%20Application%20Treatment%20Alternatives%20(1).doc?hsLang=en)** #### A Customized Solution The selection of the stabilizing agent best for your unique brownfield will depend on numerous variables, including dose requirements, moisture content, material permeability and grain size distribution, material type, project location, material reuse and disposal methods, and post-stabilization pH and toxicity objectives. Treatability studies will determine the best reagent and dose requirements.

Project Pictures 029](https://www.soilsolutions.info/hubfs/Misc.%20Project%20Pictures%20029.jpg) ## Treatment Applications The SSWT wet reagent application is flexible and treatment methods can be designed to meet a variety of site specific needs. The methods can be modified to meet varying conditions while maintaining high daily output. ![SOIL-Treatment-Applications-3-1](https://www.soilsolutions.info/hubfs/SOIL-Treatment-Applications-3-1.png) Ex-Situ: #### Stockpile Treatment In the stockpile treatment method, chemical application is conducted as material is added to a stockpile ![SOIL-Treatment-Applications-1-1](https://www.soilsolutions.info/hubfs/SOIL-Treatment-Applications-1-1.png) In-Situ: #### Surficial Treatment (Depths Under 3 ft) The soil area is loosened and SSWT reagents are applied and mixed into the soil. When TCLP analysis confirms reduced levels of reachable metals, the soils can be disposed of or stockpiled. ![SOIL-Treatment-Applications-2](https://www.soilsolutions.info/hubfs/SOIL-Treatment-Applications-2.png) In-Situ: #### Deep Excavation (Depths Over 3 ft) For greater depths, treatment is conducted in a series of lifts to control the volume of soil treated. With this option, it is also possible to spray and treat buried debris. ![SOIL-Treatment-Applications-4](https://www.soilsolutions.info/hubfs/SOIL-Treatment-Applications-4.png) In-Situ: #### Small Batch SSWT can be applied for small batch applications of 20 tons or less. A small wet container with a sprayer is brought to the site so that treatment can be done in-situ. ![SOIL-Treatment-Applications-5-1](https://www.soilsolutions.info/hubfs/SOIL-Treatment-Applications-5-1.png) Ex-Situ: #### Lead Contaminated Debris ![Treatment Eval Cover Page small](https://www.soilsolutions.info/hs-fs/hubfs/Treatment%20Eval%20Cover%20Page%20small.png?width=550&name=Treatment%20Eval%20Cover%20Page%20small.png) ## Get a Soil Treatment Evaluation The key to treating your contaminated site is a team you can trust and a strategy that works the first time.
